Abstract
An efficient memory controller. The controller includes a first mechanism for associating one or more input command sequences with one or more corresponding values. A second mechanism selectively sequences one of the one or more command sequences to a memory in response to a signal. A third mechanism compares each of the one or more values to a state of the second mechanism and provides the signal in response thereto. In a specific embodiment, the one or more corresponding values are execution time code values, and the second mechanism includes a sequencer state machine that provides the state of the second mechanism as a sequencer time code. In the specific embodiment, a compare module compares the sequencer time code to a time code associated with a next available command sequence and execution time code pair and provides the signal in response thereto.
